Poisson's ratio values for rocks - ScienceDirect

The values of Poisson's ratio for some minerals are listed in Table 3. It should be noted that the number of independent elastic constants appropriate to a mineral crystal depends on its crystal symmetry, and it ranges from three for a cubic crystal to twenty one for a triclinic crystal . Therefore, for single crystals of minerals, it may not be possible to give a value for Poison's ratio.
